Trivia

What makes it special

  • Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 13.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.2 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 7642 years in a starship at a tenth of light speed.
  • Distance. 764 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1262.

Saying hello

  • Say hello. A radio message and its reply would take 1528 years round-trip.

Standing on it

  • A year here. A full year lasts about 5 Earth years.

By the numbers

  • Mass. Roughly 8359× Earth's mass — about 26.3 Jupiters.
  • Temperature. A frigid -34°C — colder than dry ice.

How we found it

  • Discovery. Found by Haute-Provence Observatory using the radial velocity method.

About BEBOP-4 AB b

BEBOP-4 AB b is a rare exoplanet. It lies about 764.2 light-years from Earth, has an equilibrium temperature near 239 K, weighs about 8,358.89 Earth masses and completes an orbit every 1,823.5 days.

Sits where it's neither too hot nor too cold — liquid water could exist.

How to see it

Like any astronomical target, BEBOP-4 AB b is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why BEBOP-4 AB b is a rare exoplanet

BEBOP-4 AB b scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.

That score comes from 2 science badges — Confirmed exoplanet and In the habitable zone — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
